Optical fibre sensors and optical fibre amplifiers are essential components in modern industrial automation for detecting and transmitting signals in environments where electrical interference or explosive atmospheres preclude the use of conventional sensors. These devices operate by modulating light through an optical fibre cable, with the sensor head detecting changes in light intensity caused by the presence or absence of an object. The amplifier unit processes the optical signal and provides a switching output, typically PNP or NPN, with adjustable sensitivity and response times. Key technical parameters include fibre type (plastic or glass), sensing distance (ranging from a few millimetres to several metres depending on the fibre and amplifier combination), operating voltage (usually 12-24 VDC), and output configuration. The amplifier often features a teach-in function for easy setup and may include a display for real-time signal level monitoring.
These sensors are widely deployed in sectors such as automotive manufacturing, packaging, food and beverage processing, and material handling. They are particularly suited for confined spaces, high-temperature zones, and areas with strong electromagnetic fields, such as near welding robots or induction heaters. Typical installation environments include conveyor systems, assembly lines, and automated storage and retrieval systems. The optical fibre cable can be routed through tight bends and harsh environments, while the amplifier is mounted remotely in a control cabinet, ensuring the electronics are protected from dust, moisture, and vibration.
Within this category, key subcategories include through-beam fibre optic sensors, diffuse reflective fibre optic sensors, and retro-reflective fibre optic sensors. Common article codes often follow a pattern such as "E32-" for fibre units and "E3X-" for amplifiers from major manufacturers, though generic equivalents are also available. For example, a typical fibre unit code might be structured as "[Series]-[Fibre Type]-[Sensing Mode]-[Cable Length]", while an amplifier code might include "[Series]-[Output Type]-[Connection Method]-[Power Supply]". Specific articles include the E32-T11R 2M through-beam fibre unit and the E3X-NA11 2M amplifier with NPN output.
